Detection of Bovine IgG Isotypes in a PPA-ELISA for Johne's Disease Diagnosis in Infected Herds

<table>Results of isotypes/PPA-ELISAs. Dotplots of IgG (a), IgG1 (b), and IgG2 (c) PPA-ELISAs. Antibody responses are plotted as mean optical density (OD); lines and numbers (over lines) represent cut-off points. Letters indicate a significant difference (<i>P</i>&lt; 0.05) between groups. Groups: healthy controls (Hc, <i>n</i> = 38), exposed (E, <i>n</i>= 30), subclinically infected (SC, <i>n</i> = 26), and clinically infected (C, <i>n</i> = 14).</table>
